Nightly construction is underway on Highway 400 in Vaughan, affecting both northbound and southbound traffic.
On the southbound collector, construction between Bass Pro Mills Drive and Highway 7 will reduce traffic to one alternating lane. The northbound express between Bass Pro Mills Drive and Major Mackenzie Drive will experience two alternating lane closures.
Both projects are scheduled to occur during overnight hours. Commuters using these stretches of Highway 400 should expect delays and plan accordingly during construction periods.
